DEVICE FOR WINDING'WEBS INTO ROLLS;

SPECIFICATION forming ia of Letters Patent No. 634,479, dated October 10, 1899.

Application filed November 16, 1896. Serial a. 612,202. (am-1.1.1

is a winding apparatus placed at the end of paper-makin g machines and operating to'wind the finishedv web or" paper as it isreceived from-the paper-machine into a suitable-sized roll for delivery or shipment. The invention is, however, applicable generally to the winding of a long web. of paper into aroll -such, for instance, as wall-paper.

The invention has for its object the making of a tight, smooth, and even roll; and it consists in certain improvements adapted to secure a more efficient and convenient construction for winding heavy rolls and includes improved means for adjusting the supporting guiding frames orways upon which the winding-shaft moves into thedesired angular position, whereby is'attained the tension appropriate to the quality and condition of the paper being wound, which adjustability, in connection with other features'ofthe machines, also enables the large and heavy rolled web, to be conveniently moved moved from the machine.

A practical embodiment of theinvention is illustrated in the'accompanying drawings, in whieh- Figure 1 is an end elevation of a machine in which the guiding frames or ways are adjusted to a'horizontal position. Fig. 2 is a like view with some'parts omitted, inwhich the guiding frames or ways are adjusted to an anguiar position." Fig.3 is a reareleva tion of the machine. Fig. i is a plan View of the machine,- and Figs. 5 and 6 are details'ot the sprocket-chains for moving the windingshaft. i

Heretofore the guide frames or w'ays'forthe Winding shaft of the forming-roll have either been placed in a horizontal position or inan angular position'with respect to a horizontal in and re plane; butthe best results are obtained when the inclinationof that angle is made a degree suited to the quality of the paper operated upon. The degree at which these guide frames or ways are inclined must therefore be varied to suit the paper which is operated upon, and

hence according to this invention they are capable of ready and accurate adjustment for that purpose. Rolled webs thus formed are large andiheavy'and consequently presentdi'fficulties in readily removing them from the-machine when the guide frames or ways stand at'an' angle to the horizontal, usually requiring hoisting-gear for the purpose. By this invention, however, the adj ustaloility of such guide frames or ways enables the formed roll to be'so readily lowered as to make it convenient to discharge it from the guide frames or ways directly onto a truck for removal.

The principal elements of this roll-winding "machine are a winding-drum A, against the periphery ofwhich the forming roll 0, of paper, restsand by which it is rotated,a windingshaft 12, carrying the roll-receivingshell or tube 11, upon which the rolled paper accumulates and by which it is supported for use, sl'iding'carriages 3 i, in which said windingshaftis journaled, and guide frames or ways 8 9, upon which the said carriages slide and are supported-and guided in their movements as the roll enlarges, said guide frames or ways-being pivoted atone end, so as to be capabie of a vertical swinging movement and provided with means for vertical adjustment,

-whereby they may bezinclined at any desirjableangle'as the .roll is forming and be depressed for its delivery when it is formed.

' The winding-drum A is an ordinary cylinder, preferably metal, having its shaft 32 mounted in suitable journal-boxes 34,-resting upon the side frames, and driven at an appropriate speed, usually from the machine from which the paper web to be wound up isreceived. The paper is wound up upon a core, shown as formed by a shell or tube 11, which shell or tube or the paper accumulated thereon constantly bears against the surface of the-winding-drum A during the formation of the roll. This shell or tube 11 is carried on a shaft 12, that is mounted at opposite ends in movable carriages, which slide on guide frames or ways 8 9. These sliding carriages each consist of a lower member 4, fitted with overhanging sidesand adapted to embrace the squared guiding portions of the ways 8 9, which lower member is provided at its upper side with a half-journal to receive said shaft and carries hinged to it at one end an upper member 3, which is provided with a corresponding half-journal, which upper member may be opened to receive the shaft or admit its removal and closed and locked to hold the same in position, as shown, said shaft being provided with reduced ends to serve as handles, one end having its extremity squared, thus suiting it to receive a winch when it is desired to revolve it by hand.

The gnideways 8 and 9 are pivotally hung upon studs or short shafts 5 b, that are journaled in the side frames, and the two guideways have their supportin g-frames connected together, so that they may be moved in unison by means of the shafts 20 and 21, which extend longitudinally through the machine. The lowermost portions of these guideways S 9 have projecting at each outer side thereof swiveling heads l-gt 15, which are provided with vertical internal threads, with which screws 16 17 cooperate in raising and lowering the guideways. These screws 16 17 pro ject vertically from journal-like heads 18 19, that are fast to a shaft 21, and have upwardly-projecting extensions in which are formed sockets for the reception of the pivots carried at the lower ends of the screw-shafts, whereby said screws are made capable of horizontal rotation. These screws carry near their lower ends bevel-wheels 22 23, that are made fast thereto. The heads 18 1.) oscillate in proper bearings furnished by pillow-blocks 24 25, and the cross-shaft 21, which carries said heads, has mounted fast upon it bevelpinions 26 27, which gear with said bevelwheels 22 23, and thus rotate the screws 16 17, while permitting them to assume slight angles of inclination. This shaft 21 is provided with loose driving-pulleys 3O 31, driven in opposite directiops by belts from driving-pulleys 35 36 on the shaft 32, between which pulleys 3O 31 (see Fig. 3) is provided a clutch 33, by which motion in opposite directions may at will be communicated to said shaft by the movements of a shifting-lever 37. This mechanism thus described is for the purpose of raising or lowering the outer ends of the guide-rails, and thus fixing the degree of the inclination of the guideways for the proper support and guidance of the roll of paper during its formation and lowering the winding-shaft carrying the formed roll of paper upon it when it is to be removed from the machine, as will presently appear.

Each sliding carriage 3 4 is provided for moving them and the rolled web they carry with a sprocket-chain 38, attached to its outer side, as shown in Figs. 5 and 6. One end of each chain is connected to a hook 1, that is carried by one member of a turnbuckle which plays through a lug 2, that projects laterally from the lower member of each carriage 3 4, and the other end of each chain is hookedto the other end of said turnbuckle, and this turnbuckle is made an adjustable elastic coupling by being provided with a spring 42, carried on the member having thehook 1, which spring bears between the lug 2 and the stop-nuts, as shown. These sprocket-chains run over sprocket-wheels 39 40, pivoted, to the inside face of each guideWay-frame at its opposite ends, and over a sprocket-wheel 41, mounted on a shaft 20, which extends through the machine and is journaled in brackets coupled to the side frames. The shaft 20 is provided at one end with a hand-wheel 43,whereby it may be turned to move said sprocketchains and adjust the position of the carriages as may be desired. This shaft 20 also carries afriction-wheel 44, around which a frictionband 45 is stretched, said band being fastened to and controlled by a lever 10, hung on the pivot 5, the band being attached at one end to said pivot and at the other end to the extremity of the short arm of the lever, and the long arm of said lever is provided with an adjustable weight 13, by which the tension of said friction-band is regulated. This lever 10 is capable of being raised toremove the friction by means'of a dog 7, pivoted to the guideway and operated by means of ahand-lever48.

The operation of this machine is as follows;

The upper members 3 3 .of the sliding carriages having been unlocked and opened, the shaft 12 is removed from its bearings and supplied with the-sh-ell or tube 11. It is then replaced in its hearings in the carriages and the upper members 3 3 thereof are closed and locked. The web of paper is then attached to the shell or tube, the shaft 12 is turned by a hand-winch sufficiently to start the formation of the roll, and the carriages are moved forward by the hand-wheel 43 and sprocketchains to bring the shell or tube 11 up to the winding-dru m A, so that the paper-clad shell or tube shall bear against its periphery. The shaft 21 is then set in motion in the proper direction to cause the screws 16 17 to so far elevate the guideways 8 9 as to give them the proper degree of -inclination, as is seen in Fig.2, to suit the formation of the roll to the quality of paper to be rolled up, when the driving mechanism by which shaft 21 was rofated is thrown out of operation and the guideways held by the screws 16 17 in the position to which they have been adjusted. The motion of the shaft 32 is then communicated to the winding-drum A by means of the shifting-lever 50 and clutches 51 52, which it controls. The winding-roll, driven peripherally, is thus formed smoothly and compactly under the tension best suited to it, the resistance to its outward travel being changed as may be'desired, by adjusting the weight 13, and when it has attained its largest size it is ready for removal from the machine. To readily accomplish this, the driving-shaft 3c is uncoupled, the web is severed, and the shaft 21 is set in motionin the proper direction to cause the screws 16 17 to turn and lower the guideways 8 9 to substantially a horizontal 'positionit may be somewhat lower-and by means of the hand-wheel 43 the sprocket-chains 38 38 are actuated to move the carriages 3 4 forward, and thus deposit the roll upon a truck entered far enough under the machine for the purpose of receiving it, during which transfer of the roll from the machine to the truck the shaft 12 will at the proper time be released from the embrace of its carriages, and the releasing of such shaft from its seat therein may be accomplished by the last part of the lowering operation after the roll has reached the truck or the lifting of the truck itself may accomplish it, it being obvious that if the members 3, carrying the upper half-journals of the shaft, are unlocked the lifting of the roll away from the guideways or the lowering of the guideways with the roll supported by the truck will resuit in the raising of these members 3, so as to release the shaft, and the raising of the latter out of the lower half of the bearings carried by the members 4.

Of course the shell or tube upon which the web is wound and by which it is adapted to be hung in the machine wherein the web is to beused would be properly acted upon and operated in this winding-machine in producing the roll if its sustaining-shaft simply rested upon and rolled over the guideways; but for the purpose of controlling its movements otherwise it is preferable to provide it with carriages, as explained. These carriages may, however, be of many constructions, and although those shown and described have advantages mere sleeves encircling the shaft would perform their office and mightcarry the hooks for attaching them to the sprocketchains.
